# Server Routes

Server adapters register these routes when you call `server.init()`. All routes are prefixed with the `prefix` option if configured.

## Agents

| Method | Path | Description |
|--------|------|-------------|
| `GET` | `/api/agents` | List all agents |
| `GET` | `/api/agents/:agentId` | Get agent by ID |
| `POST` | `/api/agents/:agentId/generate` | Generate agent response |
| `POST` | `/api/agents/:agentId/stream` | Stream agent response |
| `GET` | `/api/agents/:agentId/tools` | List agent tools |
| `POST` | `/api/agents/:agentId/tools/:toolId/execute` | Execute agent tool |

### Generate request body

```typescript
{
  messages: CoreMessage[] | string;       // Required
  instructions?: string;                   // System instructions
  system?: string;                         // System prompt
